ELECTRONIC THROTTLE CONTROL (ETC)

ETC OPERATION OVERVIEW

IMPORTANT
DO NOT attempt to service the ETC. The ETC is a non-
serviceable component and can only be tested using
Digital Wrench®. If the ETC is faulty, the entire
assembly must be replaced.
Mounted to the intake plenum, the ETC acts as an
electronically controlled throttle body. The ETC controls
engine throttle operation to provide the proper airflow
needed for engine operation at all RPM ranges. The ETC
controls engine RPM based off input provided by the
Pedal Position Sensor (PPS) and Electronic Control Unit
(ECU).

ETC TEST

Never attempt to disassemble the ETC assembly.
Warranty is void if the end cover is opened or tampered
with in any way.
All operating and control functions within the ETC are
pre-set. No internal servicing or adjustments may be
performed. If a problem is encountered, and you
determine the ETC to be faulty, contact the Polaris
Service Department for specific handling instructions. Do
not replace the ETC without factory authorization.
Use Digital Wrench® to perform all troubleshooting of
this component. Use a Volt Ohm meter to test the vehicle
harness continuity between the ETC connector and ECU
connector. Refer to the wire diagram for pin-out details. If
the ETC is faulty, the entire ETC assembly must be
replaced.

ETC REPLACEMENT

NOTICE
The ETC is a non serviceable component and can only
be replaced with the entire throttle body. Refer to
Throttle Body Service page 3.15.

ETC LEARN PROCEDURE

IMPORTANT
This procedure MUST be performed on the vehicle
whenever the ECU is replaced or reflashed or the
throttle body is replaced.
1. After the reflash / ECU replacement / throttle body
change, leave the key on (engine not running) for 60
seconds. Do NOT crank the engine during this time.
2. Turn the key off and wait 3 minutes. During this time,
the ECU will write values into memory and then
completely shut down.
3. Turn key back on and start the vehicle. The vehicle
should operate normally.
4. If the procedure was interrupted at any time, start
back at step 1.
